pull: pass verbosity, --progress flags to fetch and merge

7f87aff (Teach/Fix pull/fetch -q/-v options, 2008-11-15) taught git-pull
to accept the verbosity -v and -q options and pass them to git-fetch and
git-merge.

Re-implement support for the verbosity flags by adding it to the options
list and introducing argv_push_verbosity() to push the flags into the
argv array used to execute git-fetch and git-merge.

9839018 (fetch and pull: learn --progress, 2010-02-24) and bebd2fd
(pull: propagate --progress to merge, 2011-02-20) taught git-pull to
accept the --progress option and pass it to git-fetch and git-merge.

Use OPT_PASSTHRU() implemented earlier to pass the "--[no-]progress"
command line options to git-fetch and git-merge.
